Newsletter: scaffold the wp-build dashboard chassis behind the flag by keoshi · Pull Request #48574 · Automattic/jetpack

keoshi · 2026-05-06T14:59:58Z

Part of #48530 — second of six PRs to modernize Jetpack's Newsletter into a unified wp-admin product. Builds on #48532 (the empty wp-build scaffold + feature flag) by establishing the runtime chassis the next four PRs sit inside.

Proposed changes

Replace the placeholder <h1>Newsletter</h1> stage with Page chrome from @wordpress/admin-ui. Body is still empty — Subscribers DataView lands in PR 3, the Settings tab in PR 4.
Wrap the Stage in a @tanstack/react-query QueryClientProvider with a shared queryClient (30 s staleTime, no refetch-on-focus). Picking React Query here, not @wordpress/data core-data, matches the prototype (#48420) so PR 3 can drop the existing Subscribers data hooks in unchanged.
Lift analytics.initialize() from NewsletterSettingsApp into the route Stage, so future Tracks events (jetpack_newsletter_tab_view etc.) fire regardless of which tab a visitor lands on.
Add an empty Inspector slot at routes/dashboard/inspector.tsx so the route hook can target a stable surface. The subscriber detail panel lands inside it in PR 3.
Wire the route.inspector hook to a subscriber / u URL param (Boolean( search?.subscriber || search?.u )) — boot's router calls this on every navigation and uses the boolean to decide whether to render the inspector. Returns false at runtime today (no subscriber selection UI yet); PR 3 enables it.

All gated behind rsm_jetpack_ui_modernization_newsletter. With the flag off, the legacy Newsletter Settings page renders unchanged.

Umbrella: Newsletter: modernize into a unified wp-admin product (six-PR sequence) #48530
Previous PR: Newsletter: add empty wp-build dashboard scaffold behind feature flag #48532 (scaffold + feature flag)
Working reference (superseded): Newsletter: unify Subscribers + Settings into a single wp-admin product #48420
Cadence model: VideoPress: add empty wp-build dashboard scaffold behind feature flag #48494 (VideoPress wp-build scaffold)

Does this pull request change what data or activity we track or use?

No. The analytics initializer is moved, not changed; the only Tracks-related delta is where analytics.initialize runs — same call, same args. No new events fire.

Testing instructions

Pull this branch, run pnpm install and pnpm run build from projects/packages/newsletter/. Then verify both flag states:

Flag OFF (regression check)

Make sure no add_filter( 'rsm_jetpack_ui_modernization_newsletter', ... ) exists in any mu-plugin / wp-config.php / theme.
Visit wp-admin/admin.php?page=jetpack-newsletter.
Confirm today's Newsletter Settings page renders exactly as before — analytics.initialize still fires from NewsletterSettingsApp (untouched by this PR), <div id="newsletter-settings-root"> mount point is present.

Flag ON (new chassis)

Add the following to a mu-plugin, wp-config.php, or use the Code Snippet plugin:
```
add_filter( 'rsm_jetpack_ui_modernization_newsletter', '__return_true' );
```
Hard-refresh wp-admin/admin.php?page=jetpack-newsletter.
Confirm a "Newsletter" page header renders inside the standard wp-admin chrome (sidebar visible). The body is still empty — that's expected; PR 3 fills it in.
DevTools → Network: wp-build's bundle (under build/scripts/ or build/pages/jetpack-newsletter-dashboard/) loads, not the legacy newsletter.js.
No console errors. analytics.initialize fires exactly once per page load (check Tracks in DevTools → Network or window._tkq to confirm a single record payload on init).

Toggle round-trip

Comment out the add_filter line and refresh — legacy Newsletter Settings page should return immediately.
Re-enable the filter and refresh — new chassis should return. Both directions reversible without cache clears.

…ready fired `WP_Build_Polyfills::register()` adds its registration callback to `wp_default_scripts`, but that action only fires once — when `wp_scripts()` is first instantiated. On admin requests where any earlier-loading plugin touches `wp_scripts()` before `admin_menu` priority 1 (where consumers like Newsletter call `register()`), the hook arrives too late and the polyfills never register: dependent script modules like `@wordpress/boot` and classic scripts like `wp-theme` go missing, the boot loader's `<script type="module">` tag is never printed, and the wp-build chassis fails to mount on a blank page. Detect that case via `did_action( 'wp_default_scripts' )` and run `register_scripts()` + `register_modules()` synchronously on the live `wp_scripts()` instance, so the polyfills land regardless of init order. Surfaced while testing Newsletter's modernization chassis (PR #48574) on a Docker site where Jetpack JITM enqueues scripts during `plugins_loaded`, instantiating `wp_scripts()` before `admin_menu`.

LGTM. Rebased,

The page-shell scaffolded in #48574 now renders the Subscribers list: the Stage wraps `<SubscribersBody>` (selection, modals, header actions) inside the existing `<Page>` chrome and `QueryClientProvider`, adds the page subtitle, and pulls in `route.scss` for the identity cell, inspector chrome, and detail layout styles. The route still has no tabs — Settings stays on its legacy surface behind the modernization filter until a later PR. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Replaces the empty inspector with `<SubscriberDetailContent>` reading `?subscriber=…&u=…` from the URL — boot's router already gates the mount on those params via `route.inspector` (added in #48574). Wraps the slot in its own `QueryClientProvider` so subscriber-detail queries share the cache the stage has already warmed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…#48581) * Newsletter + Forms: lift Gravatar into @automattic/jetpack-components The Gravatar component (with hovercard support, SHA-256 hashing, and a configurable defaultImage) moves into @automattic/jetpack-components exposed at the `./gravatar` subpath. Forms switches to it; the local copy in `projects/packages/forms/src/dashboard/components/gravatar/` is removed and the `@gravatar-com/hovercards` and `js-sha256` deps move with it. Sets up Newsletter's Subscribers port to consume the same shared component. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Newsletter: add REST proxy for the Subscribers admin page Adds `WPCOM_REST_API_V2_Endpoint_Subscribers_List` registering `/wpcom/v2/subscribers/{list,individual,totals,stats,add,remove,products,comp,remove-comp}`. Each route proxies to the corresponding WP.com endpoint via `Automattic\Jetpack\Connection\Client::wpcom_json_api_request_as_user`. The wp-admin Newsletter page (next commit) consumes these endpoints to render the Subscribers DataViews table and per-subscriber actions on Jetpack-connected self-hosted sites. Glob-loaded by `load-wpcom-endpoints.php`, so no loader changes. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Newsletter: add the Subscribers data layer + library helpers Ports the non-rendering plumbing from #48420's Phase 2 into `_inc/subscribers/`: - `data/api.ts` + `data/types.ts` — REST client + DataViews/API types. - React Query hooks for list, individual, totals, stats, add, remove, comp / remove-comp, and memberships products. - `lib/` helpers: CSV parsing, DataViews i18n, site context, subscriber helpers, subscription plans + status, Tracks events, and the DataViews `View` <-> URL state hook. No UI yet. The list, cells, modals, and detail pane (next commit) consume these hooks. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Newsletter: add the Subscribers DataViews UI Drops in the rendering layer ported from #48420: - `subscribers-data-views.tsx` — the table/list with fields, filters, pagination, row actions, and bulk actions. - `subscribers-body.tsx` — selection, modal orchestration, and the `<SubscribersDataViews>` mount. - `cells/{subscriber-identity,subscription-status-cell,subscription-type-cell}` — column renderers (identity uses the shared `Gravatar`). - `detail/subscriber-detail-content.tsx` — sliding inspector content with joined date, status, and email engagement stats. - `modals/{add-subscribers,comp,remove-comp,unsubscribe}-modal` — row + bulk action dialogs. - `header-actions.tsx`, `empty-state.tsx`, `jetpack-logo.tsx` — page chrome accents. Not yet mounted; the next commit wires `<SubscribersBody />` into the route Stage. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Newsletter: mount the Subscribers DataViews in the dashboard Stage The page-shell scaffolded in #48574 now renders the Subscribers list: the Stage wraps `<SubscribersBody>` (selection, modals, header actions) inside the existing `<Page>` chrome and `QueryClientProvider`, adds the page subtitle, and pulls in `route.scss` for the identity cell, inspector chrome, and detail layout styles. The route still has no tabs — Settings stays on its legacy surface behind the modernization filter until a later PR. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Newsletter: render the subscriber detail in the inspector slot Replaces the empty inspector with `<SubscriberDetailContent>` reading `?subscriber=…&u=…` from the URL — boot's router already gates the mount on those params via `route.inspector` (added in #48574). Wraps the slot in its own `QueryClientProvider` so subscriber-detail queries share the cache the stage has already warmed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Newsletter: changelog for the Subscribers DataViews port Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Newsletter Subscribers REST: gate routes behind the modernization filter + add tests Until the dashboard UI ships, register no /wpcom/v2/subscribers/* routes unless `rsm_jetpack_ui_modernization_newsletter` is on — same gate the wp-build page already uses. The check lives inside `register_routes()` (which fires on `rest_api_init`) so theme- or plugin-added filters are applied before it evaluates, instead of at file-load time when only mu-plugins have run. Adds a focused test class covering the new gate, the cap check (anon and under-privileged users), and the handler-level input validation paths in `add` / `remove` / `individual` / `stats` — the layers most likely to silently regress without coverage. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Newsletter Subscribers: harden CSV download link + cover remove-mutation Pass `noopener,noreferrer` to `window.open` for the page-header CSV download — matches the pattern used everywhere else we open a new tab. Adds Jest coverage for `useSubscriberRemoveMutation`: singular vs bulk snackbar copy, the partial-failure path that emits both success and error notices, and the MAX_BULK_REMOVE cap that protects WP.com from a runaway selection. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix changelog * Jest configs: allow @gravatar-com CSS through transformIgnorePatterns Lifting `Gravatar` into `@automattic/jetpack-components` made every package whose tests touch that components index transitively evaluate `gravatar/index.tsx`, which side-effect imports `@gravatar-com/hovercards/dist/style.css`. Jest's default behavior is to skip `node_modules` for transformation, so the CSS reached the JS parser and blew up with `SyntaxError: Unexpected token '.'` across publicize, social, and the plugins/jetpack admin-page tests. Two configs maintain their own allowlists: the shared base config in `tools/js-tools/jest/config.base.js`, and the plugins/jetpack gui runner at `projects/plugins/jetpack/tests/jest.config.gui.js`. The gui runner's local pattern overrides the base via `transformIgnorePatterns` set semantics (union — any matching pattern wins, so a local "ignore" beats a base "unignore"), so both need the same allowlist entry. Adds `@gravatar-com` to both alongside `uplot` and `@wordpress/admin-ui`.
